<p><code>it prevents rustc from bootstrapping on windows-msvc.</code> I would probably mark it as P-Critical, at least P-High</p>

<p>it only occurs in developing, P-critical seems a bit too high for me</p>

<p>Agree. P-high should be fine</p>

<p>If it prevents the compiler from bootstrapping and this were to reach beta, does that mean we would be unable to build stable for release on Windows?</p>
